My italicized "obviously" in the above quote was intended to convey sarcasm. Not sure that it worked now :(

Anyway, yes, I'd heard he had been at least planning for a rewrite, though I didn't know he'd made much progress. Interestingly, another thing I'd read was that he planned on changing all references to "goblins" in the Hobbit to "orcs," as they are supposed to be the same creatures. However, many have interpreted them to be smaller and less fearsome, given their more childish nature in the books. But initially the distinction is not so clear.

I encourage you to read the books, xhonzi. You might enjoy the differences and the resulting approaches Jackson and Co. took to the different films. I think splitting it (as Kbrana said) was the right choice for Jackson, and the only childishness that really did bug me was the bird poop on Radagast.

Bit of trivia: Gandalf can't remember the names of the two blue wizards in the film. This is likely because their names were not completely consistent, and the only sources for their names are from incomplete stories. It was a joke based on the two different versions of their names.
